Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or...

The stresses that come with aging, chemotherapy treatments, and environmental exposures all threaten fertility. But what if there were a way to preserve women's limited egg supply? Researchers reporting on studies conducted in frog and mouse eggs in the Cell Press journal Molecular Cell on October 3rd may have found a way. The findings come at an important time when many women are waiting longer and longer to have children, renewing interest in the development of strategies to preserve...

Scientists Discover Aneuploidy In Single-celled Organisms
2013-08-14 14:57:39

University of Luxembourg Baker's yeast is a popular test organism in biology. Yeasts are able to duplicate single chromosomes reversibly and thereby adapt flexibly to environmental conditions. Scientists from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg, in collaboration with colleagues from the US Institute for Systems Biology (ISB) in Seattle, have now systematically studied the genetics of this process, which biologists refer to as aneuploidy. The...

Tiny Single-celled Organisms Have Amazingly Complicated Social Lives
2013-07-30 09:06:00

Washington University in St. Louis In 2011, Nature announced that scientists had discovered a single-celled organism that is a primitive farmer. The organism, a social amoeba called Dictyostelium discoideum, picks up edible bacteria, carries them to new locations and harvests them like crops. D. discoideum enjoyed a brief spell in the media spotlight, billed as the world's smallest farmer. Now a collaboration of scientists at Washington University in St. Louis and Harvard University...

Ossabaw Island Hog
2014-09-02 09:37:37

The Ossabaw Island hog, also known as the Ossabaw Island, is a breed of pig that developed from a herd of feral pigs on Ossabaw Island, Georgia in the United States. The original population of hogs was brought to the island by the Spaniards during the sixteenth century for the purpose of later consumption, which was a typical practice during Spanish exploration at that time. The pigs became isolated on the island for hundreds of years and had little interaction with domestic pig breeds or...

Auckland Island Pig
2014-08-07 11:44:58

The Auckland Island pig is a breed of feral pig that resides on Auckland Island in New Zealand. During the eighteenth and nineteenth centuries, domestic pigs were released onto many sub-Antarctic islands, including Auckland Island, by Europeans who wanted stranded sailors or whalers to have a steady supply of food when visiting these uninhabited islands. This process began in 1807 and after several other releases occurring between 1840 and the 1890’s, the pigs began to establish a healthy...
